ANNIE ACKER, OF SAN FRANCISCO, CALIFORNIA, ADMINISTRATRIX OF THE ESTATEOF FREDERICK AOKER, DECEASED.

IMPROVEMENT IN BUNG-STAVES FOR BARRELS.

Specification forming part of Letters Patent No. 45,553, dated December20, 1864.

To all whom, it may concern..-

Be it known that I, ANNIE AcKnR, of San Francisco, in the county of SanFrancisco and State of California, and administratrix of FREDERICKAoKER, deceased, who resided in the same place, do hereby declare thatFRED- ERICK ACKER aforesaid did invent certain new and usefulImprovements in Gasks for Holding Liquids; and I, for the purpose ofobtaining Letters Patent therefor, as administratrix, and intrust forthe heirs of said FREDERICK ACKER, do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings, making a part of this specification, inwhich- Figure 1 is a longitudinal section of the metal portion of astave and bung pertaining to the same, taken in the line mm, Fig. 2;Fig. 2, an external or face view thereof; Fig. 3, an end view of thesame.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to a means employed for preventing the cask beinginjured by the removal'of the bung. The ordinary wooden bung, as is wellknown, requires to be started or loosened by striking the stave inwhichit is fitted by means of a mallet or hammer, and this operation,after being repeatedly performed, injures and breaks or splits thestave. To obviate this difficulty is one of the objects of thisinvention, and to efiect such result the whole or a portion of the stavein which the bung is fitted is constructed of metal and fitted betweenthe wooden staves in a firm and substantial manner, as hereinafter setforth.

To enable those skilled in the art to fully understand and construct theinvention, I-will proceed to describe it.

A, Figs. 2, 3, and 4, represents a metal portion of a stave, in which ascrew-bung, B, is fitted, said bung being provided with a shoulder, (1,which, when the bung is fully screwed into the bung-hole, bears againsta leather or suitable packing, I), as shown clearly in Fig. 2.

The ends of the metal portion A of the stave have each a groove, 0, madein them to receive tenons out or formed 011 the inner ends of the woodenparts of the stave, as shown clearly in Fig. 2, the ends of the woodenportions of the stave being shown in red. The sides of the metal portionA of the stave may be provided with longitudinal cleats d, (see Fig. 3,)to fit into' the sides of the adjoining wooden staves and keep the metalportion A firmly in position. The bung B is also constructed of metal,and provided with a square recess, 0, to receive a key for the purposeof screwing the bung into A and unscrewing it therefrom. (See Fig. 2.)By this means it will be seen that all trouble and difficulty attendingthe fitting of the bung into the cask and removing it therefrom areavoided. The stave cannot be split or injured in any way, and the metalportion A may be applied to old as well as to new casks. The centralhoops of the casks may be made to fit over the joints formed by thejunction of the ends of the metal parts A and the wooden parts of thestave. These metal parts A may be of cast-iron, and patterns ofdiiferent sizes are designed to be made in order to obtain castings ofdifferent sizes to suit different-sized casks. A full-length metal stavemay be used and applied in the same way as a wooden one, but the metalsection is preferable.

Having thus described the invention, what is claimed as new, and forwhich Letters Patent are desired, is-

The metallic stave or segment of stave A, provided with longitudinaltongues d d, and threaded for the reception of a screw plug or bung, B,substantially as herein described.
